Answer

Brief Explanations:

The chart shows U.S. greenhouse - gas emissions by gas from 1990 - 2013. Questions about the data in the chart, like why CO₂ emissions are high or why they stayed constant, help clarify the evidence. Questions about natural sources (not shown in chart) or punishment of industries are not relevant to clarifying the chart evidence.

Answer:

C. Why are carbon dioxide emissions so much higher than other greenhouse gases? D. Why did the quantity of carbon dioxide emissions stay constant throughout the period?
